Ronald and his friends going on a camping trip in the Far-Flung Forest where Ronald discovers an old house which he assumes is haunted by a ghost called the Far-Flung Phantom. The campers are forced to stay in the old house due to the stormy weather where a holographic head named Franklin leads them through a challenging game which will eventually help them to escape.
The plot features Ronald and the gang out on a journey to Grimace Island where Grimace's species is discovered. Grimace previously received a letter which was actually written by the pirate captain One-Eyed Sally and her first mate Blather. The two pirates follow them to capture the treasure on the island.
While helping Franklin clean up his father's lab, Ronald and his pals stumble across a time machine. Hamburglar dreams up a crazy scheme to use the time machine to get out of cleaning and they end up getting lost in time. Their time travel adventures take them to prehistoric times where the time machine is nearly digested by a Tyrannosaurus and they meet their cavemen ancestors, the medieval times where they impress the crabby King Murray with a musical number to save captured Birdie, the wild wild west where they discover Hamburglar's ancestor Henry H. Burglar II, whom the residents mistake Hamburglar for, and the disco era of the '70s where they briefly encounter Mayor McCheese.
A young boy receives a magic paintbrush as a gift, which can make anything he draws come to life.
The gang travels to Scotland where a scientist attempts to build a replica of the Loch Ness Monster. Birdie befriends the Loch Ness Monster who wants his existence to be kept a secret.
A family of aliens kidnaps the Hamburglar, and it's up to Ronald and the gang to save him!
It's Ronald's birthday and Hamburglar, upset that he didn't get Ronald a present, invites everyone to a fake amusement park known as "Birthday World" to celebrate, run by an evil mad scientist named Professor Thaddeus J. Pinchworm. Everyone is amused at first, but they can no longer escape and no longer fall for the poor designs of the rides until they ride a rollercoaster which turns them into babies (both Franklin and Tika are wearing diapers) and they need to find out how to return to their original ages, even though their certain abilities are limited since they are toddlers.
It's yo-ho-ho and the bottle of fun when Ronald and his McDonaldland pals pop into a magic Tresure Island storybook, and set sail on a search for buried treasure.
Ronald and the kids go outside and play with their bicycles, scooters, and skateboards. They also warm-up and play soccer and fly Kites. Ronald McDonald shows the kids his skateboard, which he mistakes for a unicycle. The kids point out his mistake and Ronald then brings the big wheel labeled "Get Up and Go" so the activity of the day is chosen. Ronald picks Jamal to spin the wheel and it lands on wheels. All the kids pick their favorite rides with wheels except for one girl named Kim, who is unsure if she is good enough at it.
